The production center, located next to the Zirovski mine, was completed in 1984, and operated from approximately 1984 until 1990. In totally the center produced approximately 452 tons of uranium ore concentrate from relatively low grade ore (less than .1% U3O8) that was excavated at the Zirovski mine. The facility consisted of a main process building, at least four other process buildings, solvent extraction and temporary disposal areas, and a truck loading site. In 1996 plans for permanently dismantling and disposing of uranium tailings as well as contaminate equipment were being developed.
